Capristo Audi S4/5 (B8) - Valved Exhaust with Mid-Pipes (CES3)

*This System fits BOTH the V6 and V8 Models of the B8 chassis*

The iconic CAPRISTO Valved Exhaust System offers the best of both worlds through its capability to produce an aggressive exhaust note under acceleration, and a more subdued sound for city driving.

  • On the V8 models Capristo's exhaust shows a massive 20hp increase in performance/torque over the entire speed range and the sound gets an aggressive V8 rumble.
  • With the V6 engines, there is a significant increase in torque in the lower speed range. The sound is significantly more aggressive compared to the standard system. Cat replacement and muffler replacement are the prerequisite for performance increases (control unit optimization). The tube diameters are larger than the original.

This feature is possible using vacuum-actuated valve flaps that open and close depending on driving conditions and input from the driver. At lower engine speeds and during cruise operation the valves are closed and produce a deeper exhaust note. At wide-open throttle, the valves open releasing the full symphony of the engine.

The exhaust valves are backpressure-controlled and user programmable via the included CES-3 Control Module. The programmable control unit provides 3 modes operated via a remote key fob:

Cruise Exhaust valves open at higher RPMs

Sport Exhaust valves open at lower RPMs and hard acceleration

Open Exhaust Valves Remain Open

Both the Cruise and Sport mode can be individually programmed for specific backpressure allowances to determine when the exhaust valves open. This allows precise control of the exhaust based on the drivers personal tastes and tolerance.

CAPRISTO Exhaust systems are engineered and manufactured utilizing advanced 3D Laser-Scanning, CAD Design, Digital prototyping, and CNC-bending/milling at our factory in Germany. Each system is made of high-grade T309 (1.4828) Stainless Steel and hand polished to a mirror finish. After extensive research, this specific alloy was chosen for its sonic resonance properties, low weight, and durability which are close to the properties of Inconel (used in F1).


*The exhaust system is designed to be installed directly into existing OEM mounting points*
